IMPROVEMENT IN DOOR-SPRINGS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, CXRS W.v SALADEE, vof Newark, county of Licking, State of Ohio, have invented a I new and improved f-Mode of Constructing'Springsv for Closing -Doors and Gates; and I do hereby declare that` the following is a full and e'xact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

. The'nature of my invention consistsy First. In the peculiar arrangement hereinafter shown and described, of connecting the arm B to the head of `the mandrel c, gs. 1 and 2, plate il, for the purpose of regulating the tension ofthe spring. I K Second. In. that of securing Ythe end'of. the arm Bl to the door or gate, by means of a stirrup, F F, jointed to the end of the arm, in such manner as to discard the use ofthe friction-roller generally applied to the outerend of the arm to operate against the door'or gate, and invsueh manner tha-tthel end of the arm may be instantly .disengaged from the stirrup, or its equivalents, connecting it to the door,`as hereinafter shown and described.

Third. In that f bending the butt end of the arm in such manner as to allow the door toswing back against the partition or wall in which the door-frame -is set, when the spring isapplied in suchv manner as topull the door or gate shut,`in place of pushing it shut. And I will here state that by this arrangement of the straight arm B, as shown on plate 1, and the bent arm on plate 2, I' am enabled to either push the door or gate shut, or by placing the boxA upon the side ofthe frame J', as shown on plate 2, pull it shut.

In the drawings- Figure 1, plate-1, is a complete view of the spring, with straight arm when applied so as to push the door; and

door or gate. v

Figures 1 and 2, plate 2, represent the samewith bent arm, and applied in such mannenas to pull the Figure 2, plate 1, is a top view of the box or easing A, with the topbroken off so as to expose the .a1-range arm B, and the nut or tap D, holding the arm in position. Y

Figure Bis an end view 'in section of the box o'r casing A, spriral spring E, and mandrel C, arm B in position, and the stirrup F F connecting the outer end E'1 to the door or gate.

The construction and operation of my completedoor and gate-spring are substantially as follows: lThe box or ,casing A is formed as shown in the drawings, or may be of any other design which the fancy may suggest. The mandrel is made to extend the full length of the box A, and the upper end of the mandrel is provided with the' collar K, or its equivalent, (see iig. 2,) for the purpose of receiving and holding the upper end of the spiral spring E, and is finished by forming the head Cl 'so as to make a tenen toreceivi'e the butt end of the arm B. This tenen maybe square, orany other form that will answer th'e purpos e (secco o o, figs. I and 2,) and in the end of this tenen is cast a small' pin upon which is cut a thread to receive the acorn-shaped tap or nut ment of the spiral springE, mandrel. C, collar-K, and plate I, and the head C of the mandrel C, a piece of the D, which holds the arm B in position on the mandrel, as shown. In the lower or rear 'end of the box A, I iit` the loose plate I, which is about three-sixteenths of an inch lthick, and conforming in shape to the inside of the box, and through the centre of which is pierced ,the hole to receive the lower end of the mandrel C. This plateI is also made to serve for the fastening of the lower end of the spiral spring E. -The arm B, I make in two ways: When the box is applied to the casing of the door, or hinge part of the gate, on the side to which the door or gate opens, so as to push it shut, I use tlie'straight arm shown on plate 1. But when the box A is vsecured to the inside ofthe casing ofthe door or post of theigat'e, as shown on plate 2, so as to pull the door or gate shut, the arm is bent at or near the end secured io the mandrel, so as to admit of the door being thrown wide open.4 I thus have the double advantage, in one and the same spring, of eitherpushing or pulling shut the door or gate. 1 This, I claim, is a new feature in springs used for this purpose, and gives a decided advantage in its application; for if the finish of the casing ofl the door or gate on the side to which it swings is such as to forbid the application of the bo'x A, as shown on plate 1, to push the door, I can then resort to the bent arm, shown on plate 2, and place the box A on the casing on the oppositeside of the door and pull the door shut, as will be seen by reference to plate 2 of the drawings, The butt end of the arm B has a hole pierced through it to correspond with the shape and size of the tenon on the top end of the mandrel C, and is secured in its position by the nut or tap D, shown on plate 1. The-,outer'end of the arm B may be secured to the door, when used to pull it shut, by means of a friction-roller and guide, as shown by figs. 1, and 2, plate 2. But as by 4this operation the friction-roller has a tendency to makeconsiderable noise, I prefer making-this connection by means of thejoints 7 and 9, figs. 1 andlS, plate 1, and the stirrup F F, substantially as shown. This arrangement of securing thel outer end Bl of the arm to the door or gate, possesses at once two very imbortant advantages over that of anyothelr known device for doing the s'ame, viz first, by the interposition of' this stirrup FF, working upon the two pivot-joints 7 and 9, one end of. the stirrup connected to the end Bl of the arm, (plate 1,) and the other to the door or gate by means of the plate'H, We obviate thcfrietion that attends the ilse of the friction Aroller in the end of I the arm, orlwhcn left torub against-thc door upon a. friction-plate, and We also get lrid of the',noisel of a friction-roller.; and second, by the use of this stirrup we` can so arrange the joint 4working in the end Bl of the arm, (plate 1,) as to disconnect the arm from the stirrup, and thus leave the door to swing free of the spring, when that is desired. This arrangement of' the armB and stirrup F F is susceptible of a great variety of ornamental design. The tension of the spring is regulated by'renioving the arm B from the tenen of themandrel C, and with a'wrench or other suitable implement, the head C of the mandrel'is taken hold of and forced around until the tension of the spring is as strong as desired, when the arm is replaced andthe tap ornut D is screwed down upon it. l v ,u I r Having thus fully described tny invention, what I claim'as new, and desire to secure by Letters Patent, is-

The combirrationof the box A, mandrel C, spring E, and plates D and K, witharm B and stirrup F, con-V structed and operating substantially as described and for the Vpurposes set forth.
